Ultra compact and lightweight, these under-sink tankless water heaters are designed to provide an endless supply of hot water to one or more sinks. Enjoy the benefits of 98% efficiency with no stand-by loss. This versatile unit has the ability to be mounted at any angle, allowing for flexible 360 degree installation in tight spaces like underneath counters. The Tronic 3000's compact design allows it to be wall mounted right under the sink, taking up minimal space. Because these high-efficiency units run on electricity and do not store water, there is no venting and very little maintenance is required. With significant space and energy savings, this under-sink water heater is an excellent choice for your point-of-use residential or light commercial applications.
